    Default direct rendering only as root

    whith Opensuse11 and ATI 8.5 drivers output of glxinfo when logged in as root is "direct rendering: Yes".
    when logged in as user the output is "direct rendering: No".

    When root runs fgl_glxgears it works, as user it dosn't.

    where is the problem? what can I do?
    why can only root use direct rendering?

    Thanks for the replies.

    Either you dont have those lines in /etc/X11/xorg.conf:

    Section "DRI"
    Group "video"
    Mode 0660
    EndSection

    or your user account doesn't include the group video.

    the problem is , the user is a domain-user and i don't know how to add to a local group.

    but with local users it works.

    any hints?

    Yes, but setting permisssion to 666 for group video breaks
